Frequently Asked Questions

Common questions about GBR to PDF conversion

How does in-browser GBR to PDF conversion protect my privacy?

Unlike legacy file converters that upload your confidential files to cloud servers, OpenFileConverter runs 100% locally on your computer or phone using Rust WebAssembly. Your original GBR files never leave your device memory, guaranteeing zero retention.

What is the main difference between GBR and PDF?

GBR (Gerber RS-274X PCB Photoplotter Format) provides pcb manufacturing, cam tooling, solder mask inspection, and copper layer plotting, while PDF (Portable Document Format) is optimized for multi-page documents, contracts, archivals, and print-ready proofs. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting GBR to PDF degrade visual quality?

No. OpenFileConverter uses high-fidelity chroma subsampling with configurable quality levels (default 92%), ensuring virtually indistinguishable image fidelity with sharp edges and rich colors.

Can I convert multiple files in batch?

Yes. You can drag and drop up to 100 files simultaneously. Because processing executes in parallel on your local CPU threads, batch jobs finish in seconds without queue wait times.
